I agree that macOS has become worse, however your examples don't really count:

Window snapping was implemented some time ago: https://www.macrumors.com/2024/06/12/macos-sequoia-window-ti...

Instead of win key, you can press F3, or just set a hotkey that works for you in the System Preferences

Instead of clicking the red maximize button, you can double-click the window header / title. This will use an algorithm to try to resize the window to the best size for its content.

Option-click green button does window maximise (normal click does full-screen)

You can also hold ALT and press the green button to mazimze.

		The app still gets to decide though! Most programs do go full size with an alt+green click, but not all. A column-style Finder window, for example, seems to go taller but no wider.

Maximize is green. (Any chance you might be color blind?)

		Green is “Zoom window to fit content”, not Maximize.
